 ation in the Time of Tension(s)\nProf. Dr. Goran Djordjević është profe
 sor në Universitetin e Nishit\, Serbi\, dhe Drejtor Ekzekutiv i Qendrës 
 SEENET-MTP. Ai është një studiues i njohur në fushën e fizikës teori
 ke dhe kozmologjisë moderne\, me fokus në kozmologjinë e inflacionit\, 
 vrimat e zeza primordiale dhe universin e hershëm. Ka botuar mbi 150 puni
 me shkencore\, përfshirë rreth 45 artikuj në revista SCI\, me më shum
 ë se 2000 citime. Studimet master dhe doktoraturën i përfundoi në Univ
 ersitetin e Beogradit\, ndërsa ka qenë studiues vizitor në institucione
  prestigjioze si CERN\, LMU\, MPI\, Universiteti i Freiburgut dhe CBPF në
  Brazil. Ai ka mbajtur role drejtuese në Shoqatën e të Fizikës dhe në
  Shoqatën Evropiane të Fizikës. Prof. Djordjević është bashkëthemel
 ues i rrjetit SEENET-MTP\, i cili bashkon institucione shkencore nga Ballk
 ani dhe Ukraina për të promovuar bashkëpunimin në fizikën fundamental
 e. Gjithashtu\, ai ka kontribuar në zhvillimin e programeve ndërkombëta
 re të doktoraturës dhe në mbështetjen e studiuesve të rinj në rajon.
 \nAbstract\nSince the seminal works of Einstein (1915/1916) and Friedmann 
 (1922)\, cosmology has been established itself as a theoretically well-fou
 nded branch of physics. In the 1960s\, the "Standard Cosmological Model" w
 as formulated and subsequently validated by a wealth of observational data
 \, most notably the discovery of the Cosmic Microwave Background (CMB). Ho
 wever\, the model faced fundamental open questions\, which were largely ad
 dressed in the 1980s by the theory of cosmological inflation. The extraord
 inary technological progress in astrophysical measurements revealed the pr
 oblem of "missing mass" (Dark Matter) and ``the accelerated expansion of t
 he universe`` over the last few billion years (Dark Energy and the Cosmolo
 gical Constant\, Λ). These discoveries led to the complete formulation of
  the current standard model of cosmology\, the (Λ)CDM model. Today\, this
  exciting century-long journey through cosmology faces new challenges\, hi
 ghlighted by the verified Hubble tension - arising from conflicting values
  for the expansion (Hubble) rate (H(t)) of the universe obtained via two r
 obust methodologies (CMB and Type Ia Supernovae). This is further compound
 ed by recent tensions related to CMB spectrum measurements (e.g.\, from th
 e Planck mission) and the structure of the universe in very early evolutio
 nary epochs (revealed by DESI\, ACT\, etc.). The final part of this lectur
 e is dedicated to the fundamental physics of the inflationary period and t
 he Planck scale. We address the missing links between string/brane theory 
 scales and single-field (slow-roll) inflation. Specifically\, we present a
  highly accessible tachyon field Lagrangian dynamics. This approach offers
  an intriguing and\, paradoxically\, straightforward framework for student
 s and researchers alike who possess a foundational command of classical La
 grangian mechanics.\nPlease download "Biography GDJ and Announcement" at t
